Locating grounds by distribution ratio method

A method of locating ground faults on electric power transmission lines has been developed wherein the location of a fault can be determined accurately and conveniently from the percentage distribution of ground current fed into the fault from the 2 ends of the line. This method has been applied to the Pennsylvania-New Jersey 220-kv interconnection since 1930; results obtained indicate a large saving in time and expense over what normally would be involved in locating the faults by previous methods.
